我正在尝试计算第一次尝试"$last_visit"和可能的下一次尝试之间的等待时间可能是在第一次尝试的 30 分钟之后。
不确定,但代码返回当前时间大于未来时间...
<?php
function pa($arr) {
echo '<pre>';
print_r($arr);
echo '< /pre>';
}
$lastv="2014-03-31 02:30:00";
$counter['last']= $lastv." ".strtotime($lastv);
$counter['next']= date('Y-m-d H:i:s', ((strtotime($lastv))+ (30 * 60)))." ".((strtotime($lastv))+ (50 * 60));
$counter['current']= date('Y-m-d h:i:s', time())." ".time();
$counter['wait']=((strtotime($lastv))+ (30 * 60))-time();
pa($counter);
?>
结果
Array
(
[last] => 2014-03-31 02:30:00 1396233000
[next] => 2014-03-31 03:00:00 1396236000
[current] => 2014-03-31 02:57:51 1396277871
[wait] => -43071
)

你在哪个时区,但它对我来说工作正常。可能让您感到困惑的是,您用h
而不是H
显示"当前"时间,因此在一天中的这个时间(欧洲下午)它显示 5 而不是 17。
如果我纠正这一点,结果是有意义的:
Array
(
[last] => 2014-03-31 02:00:00 1396231200
[next] => 2014-03-31 03:00:00 1396234200
[current] => 2014-03-31 15:43:47 1396280627
[wait] => -45827
)
凌晨 3 点大约是 12 小时前,即不到 10 小时 = -45827
这是一个测试函数,它接受 DateTime 对象并计算等待的秒数。如果已超过等待时间,则返回零。
我已将其更改为接受字符串作为输入。我允许传递"当前时间",以便您可以对其进行单元测试,但它是可选的,延迟也是如此。
更改"立即"值以查看它现在正在工作。
